Entoloma fulvoviolaceum Noordel. & Vauras- not previously reported from Norway

-In the period 2009-2014 Entoloma fulvoviolaceum was found in at least five different locations in Holmvassdalen Nature Reserve in North Norway. The species was first described from Finland in 2003, and so far Holmvassdalen is the only place where it with certainty has been reported outside thetype locality. Details of macro- and icroscopical features and ecology are presented in the article

Psathyrella jacobssonii Örstadius (Basidiomycetes, Agaricales) – new to Norway

Psathyrella jacobssonii was first published from Sweden in 2001. In Norway the species was found for the first time in 2014, and it is so far not known outside Fennoscandia. We here record it from four localities in Norway. This paper provides a description of the material from Holmvassdalen in Nordland county, North Norway. A compilation of other finds in Fennoscandia is included

Rødsporer (Entoloma), underslekt Cyanula i Norge, med fokus på habitat og utbredelse

This is the third paper with results from the Norwegian Entoloma project 2015-2017. An overview is given of the species of Entoloma subgenus Cyanula in Norway. Cyanula includes, among other elements, many grassland fungi. This paper is part of a larger study concerning the European species of the subgenus Cyanula, including a multigene phylogeny that will be published in due course. Furthermore, a monograph with updated tax- onomic revision is recently issued. This paper focuses mainly on the species recorded from Norway with help of ITS DNA barcoding, with reference to recent collections also from Northern Sweden, with extensive notes of their habitat requirements and distribution. Altogether 53 Cyanula species are presented here, with an updated circumscription and naming. More than half of these are reported new to Norway since the start of the Norwegian Entoloma project. Of these, 18 have been described as new during the last three years, largely based on Norwegian material. Four of these are known exclusively from Scandinavia. barcoding, morphology, taxonomy, calcareous grasslands, calcareous forestsRødsporer (Entoloma), underslekt Cyanula i Norge, med fokus på habitat og utbredelseDette er den tredje artikkelen med resultater fra det norske Entoloma-prosjektet 2015-2017. Her gir vi en oversikt over rødsporer i underslekt Cyanula i Norge. Cyanula utgjør en av de største gruppene av våre beitemarksopper. Dette er del av en større studie over de europeiske artene i underslekt Cyanula, som inkluderer en omfattende fylogenetisk undersøkelseundersøkelse som snart vil bli publisert, samt en nylig publisert bok med en oppdatert taksonomisk revisjon av gruppa. Det foreliggende arbeidet fokuserer på arter registrert i Norge ved hjelp av ITS strekkoding. Også en del nylige, sekvenserte innsamlinger gjort i nordsvenske fjellområder er inkludert her. Artene presenteres seksjonsvis, med vekt på data om habitat-preferanser og utbredelse. Til sammen 53 Cyanula-arter er presentert her, med oppdatert artsavgrensning og navnsetting. Mer enn halvparten av disse artene er rapportert nye for Norge siden starten av det norske Entoloma-prosjektet. Av disse er 18 beskrevet som nye for vitenskapen de siste tre årene, i stor grad basert på norsk materiale. To av disse er kun kjent fra Norge, og ytterligere to kun fra Skandinavia.publishedVersio

Fibre caps across Europe: type studies and 11 new species of Inocybe (Agaricales, Basidiomycota)

Based on detailed morphological and genetic investigation, 11 new species of Inocybe (I. abdita, I. alcis, I. carissima, I. cryptica, I. culicis, I. mecoana, I. mortenii, I. orioli, I. rangiferi, I. sepiana and I. turfae) are described. Six of the new species are smooth-spored and five are nodulose-spored. The new species are compared to 18 type specimens, all of which are described here and for seven of which (partial) ITS sequences have been generated. For six species, namely I. griseovelata, I. lacera, I. soluta, I. subcarpta, I. tarda and I. transitoria, a lectotype, epitype or neotype was selected, and a description and a figure plate are provided for each of them. Based on our studies, we are convinced that I. albofibrillosa and I. striatorimosa are synonymous with I. soluta, while I. aurantioumbonata is synonymous with I. tarda. Furthermore, we affirm that I. longicystis is synonymous with I. stellatospora. All of the new species are supported by phylogenetic analyses. In summary, we here describe as new, verify the taxonomic status of, or provide or corroborate morphological concepts for 29 species of Inocybe. alpha taxonomy, epitypification, Inocybaceae, Inocybe, molecular systematics, neotypification nrITS, nrLSU, RPB2, type studies.Fibre caps across Europe: type studies and 11 new species of Inocybe (Agaricales, Basidiomycota)publishedVersio

Molecular and morphological diversity in the /Rhombisporum clade of the genus Entoloma with a note on E. cocles

A combined morphological and molecular genetic study of the European species within the /Rhombisporum clade of the genus Entoloma reveals a high species diversity. This group comprises typical grassland species with pronounced and welldifferentiated cheilocystidia, and a wide range of spore shapes varying from rhomboid to five-angled. To fix the concept of the classical species E. rhombisporum, a neotype is designated. Nine species are described as new to science based on the result of nrDNA ITS phylogeny with additional gap coding, and morphological characterization: E. caulocystidiatum, E. lunare, E. pararhombisporum, E. pentagonale, E. perrhombisporum, E. rhombiibericum, E. rhombisporoides, E. sororpratulense, and E. subcuboideum. The ITS sequences of the holotypes of previously described species belonging to the /Rhombisporum clade, viz., E. laurisilvae and E. pratulense have also been generated and are published here for the first time. Since many of the above-mentioned species have been misidentified as E. cocles, it seemed opportune to also study this species and to designate a neotype to fix its current concept. A key including European species is presented. As most of the species are potentially important indicators for threatened grassland communities, the 130 ITS barcodes newly generated for this study may be useful as a reference in conservation and metabarcoding projects.

On some Entoloma species (Tricholomatinae, Basidiomycota) little known or new to Norway

This is the second paper reporting major results from the Norwegian Entoloma project 2015- 2017. Here we present species that are new to Norway or little known, from the following smaller clades: Caeruleopolitum, Claudopus, Entocybe, Leptonia, Prunuloides and Sphagneti. In addition, a few species taking a somewhat isolated position in our unpublished preliminary ITS tree are presented. The following species are here reported new to Norway: E. cuboidoalbum, E. jahnii, E. percoelestinum, E. pseudoconferendum, E. ritae, and E. venustum. The synonymy of E. mirum with the older E. juniperinum, is also discussed. Entoloma por-phyrocephalum, formerly described as a variety, is now raised to species level based on its phylogenetic position.Dette er den andre artikkelen med resultater fra det norske Entoloma-prosjektet 2015-2017. I denne artikkelen presenterer vi arter som er nye for Norge eller lite kjent, fra følgende mindre grupper/klader; Caeruleopolitum, Claudopus, Entocybe, Leptonia, Prunuloides og Sphagneti. I tillegg tar vi med enkelte arter som plasserer seg noe isolert i de foreløpige fylogenetiske analysene basert på ITS. Følgende arter rapporteres her nye for Norge: E. cuboidoalbum, E. jahnii, E. percoelestinum, E. pseudoconferendum, E. ritae og E. venustum. Den svært lite kjente E. juniperinum og synonymi med E. mirum blir også diskutert. Entoloma porphyrocephalum er tidligere beskrevet som en varietet, men blir her endret til artsnivå basert på DNA-analyser.publishedVersio
